Understanding Hazards in the Central and Eastern U.S.
Research and products for loss reduction in the Central and Eastern U.S. is accomplished through partnerships among USGS and academic, government, and private partners. USGS staff are located in the Memphis, Tennessee, field office at the Center for Earthquake Research and Information (CERI), in Golden, Colorado, and in Menlo Park, California.
The map to the right shows earthquakes (circles) greater than magnitude 3.0 since 1974 plotted on the 2008 USGS National Seismic Hazard Map for the central and eastern United States. Warmer colors on this map indicate areas of higher hazard. Larger earthquakes are represented by larger circles.
The rate of earthquakes in Oklahoma has increased remarkably since October 2013–by about 50 percent –significantly increasing the chance for a damaging magnitude 5.5 or greater quake in central Oklahoma.
The 2014 Earthquake Insight Briefing will be held on Wednesday, February 19, in Washington DC. It will be held at the District Architecture Center (421 Seventh Street NW; Washington DC). This program is for non-scientists who need to know more about earthquake hazards and earthquake risks in the Central and Eastern U.S.
The USGS Earthquake Hazards Program is co-hosting this workshop with CERI and the West Tennessee Seismic Safety Commission at the University of Memphis to encourage communication, review research efforts, and seek guidance on future research priorities to achieve our scientific goals in the Central and Eastern U.S (CEUS).
Scientists have been busy studying the 2011 earthquake including the ground motions, felt area, and scouring the landscape looking for surface deformation caused by this earthquake and past earthquakes. Read about science results and activities here.
Map shows the localities where Quaternary faulting has been detected in the subsurface, and the results published in peer-reviewed scientific journals.
There is broad agreement in the scientific community that a continuing concern exists for a major destructive earthquake in the New Madrid seismic zone. Many structures in Memphis, Tenn., St. Louis, Mo., and other communities in the central Mississippi River Valley region are vulnerable and at risk from severe ground shaking. This assessment is based on decades of research on New Madrid earthquakes and related phenomena by dozens of Federal, university, State, and consulting earth scientists.
